Different validator outputs between webapp version and command line version

[tientong98]

For the command line version, I'm using
node v22.6.0
npm 10.8.2
bids-validator 1.15.0

And bids-validator doesn't return any error or warning, while the webapp does -- on the same data.

I'm using data from https://github.com/PennLINC/CuBIDS/raw/main/cubids/tests/data/BIDS_Dataset.zip, but just included the dataset_description.json, README, and sub-02 folder.

In addition, when running the webapp version, I got this error:

The number of volumes in this scan does not match the number of volumes in the associated '.bvec' and '.bval' files.
/sub-02/ses-phdiff/dwi/sub-02_ses-phdiff_acq-HASC55AP_dwi.nii.gz

However, NVols = 61, bval has 61 values, and bvec is an array with the shape of 3x61, so this shouldn't be an error.

I can look at this in a bit, but figure I'll ping @tsalo due to CuBIDS, as he might know something I don't.

And to be clear, are you using https://bids-standard.github.io/bids-validator/ or https://bids-standard.github.io/bids-validator/legacy/?

I'm using https://bids-standard.github.io/bids-validator/.

Okay, so the difference is that you're using the schema validator webapp and the legacy validator CLI.

We'll look at the data to determine if there's a bug in the schema validator or a problem with the check in the legacy validator.
